al_fixed al_fixsin(al_fixed x);
Introduced in 5.0.0

This function finds the sine of a value using a lookup table. The input value must be a fixed point binary angle.


    al_fixed angle;
    int result;

    /* Set the binary angle to 90 degrees. */
    angle = al_itofix(64);

    /* The sine of 90 degrees is one. */
    result = al_fixtoi(al_fixsin(angle));
    assert(result == 1);

Return value: Returns the sine of a fixed point binary format angle. The return value will be in radians.
